Dam,why not make the national stuff for commercial purposes ?

Simple demand and supply mechanism in play here. If they increase the supply, the price should go down. This is because the exclusivity of the rubber is diminished, so they will be less people willing to fork out 100 pounds for 1 sheet which essentially cost way less than that to make. Sure, they can make it expensive but they cant make it too expensive less no one buys. In my opinion, if they do commercialize National blue sponge rubbers, the max they sell it is at the same price as Ternergy rubbers. Or at least somewhere around there.
Edited to include the following:
-Also, they might be a contract between CNT and DHS which prevents them from selling National stuff in large quantity. Table tennis is big in China, maybe there is some government interest to ensure the CNT continues to dominate the TT scene. With exclusive equipment being one way of doing so. Thus binding DHS's hand.
-Or it could be a pure financial reason. Maybe the cost and price range of H3 national goods are not in line with DHS's strategy and thus makes no sense to produce them in large quantities.
-Really there could be many reasons and unless DHS steps up and says why, we can't say for sure why they don't do this.
